Environmental zinc borate

OurEnvironmental zinc borate has got the certificate of Iso9002 , SGS and REACH, etc. Property: White powder, without poison, flavor and corrosiveness. Doesn't dissolve in water and other organic solvent, is easy dissolved in hydrochloric acid & sulfuric acid, etc. Good thermal stability, small granule size, less specific gravity and easy dispersed. Good miscibility with most of the polymer. Fewest smoke when burning, excellent performance in inflaming retarding.

Use: Zinc borate is inorganic addition flame retardant. is better flam retarding effect and can replace antimonous oxide. Its characteristics are that it has good hot stability, and not only stops buring and vanishes smokings.It is widely used in rubber, plastic,wood,cable, coating,etc. Zinc borate,modified can completely replace zinc borate.It have the advantage of lower price and better effect stops buring and vanishes smokings. Package: Paper-plastic bag or plastic weaved bag, lined with PE bag, and net weight 25KG.
